• Computational steering: enabling interaction with simulations and to direct the solution of biomedical, chemical, and engineering time-critical problems. • Medical: investigate such complex systems as the human body with real-time, 3D computer images; visualising correlation between therapeutic targets and disease; surgical planning and simulation: virtual endoscopy; computer augmented surger...

This paper examines the method to simulate heat balances on building and urban surfaces by combining the 3D CAD-based thermal environment simulator with 3D steady RANS CFD simulations. The simulation results of the distribution of convective heat transfer coefficient in an urban canyon model are compared with that of a wind tunnel experiment. The effects of building geometries, including verand...

in this research a numerical analysis using plaxis program has been carried out to investigate the behavior of buried concrete box culverts different parameters including load types, loading locations, culvert dimensions, underlying soil specifications, and the coefficient of earth pressure- at- rest. for modeling purpose, patch loading of rtuck or military tank has been substituted to an equiv...

Abstract The dynamic response of the retaining structures is a complex issue, and major challenge in their design, especially under seismic loading conditions. So reliable efficient solution following computational approach, closer to reality, required obtain satisfactory results. Hence, this study came clarify effectiveness PLAXIS 3D program predicting performance, accuracy, reliability walls....

A computational study was conducted to investigate the unsteady quasi-two-dimensional flow around a streamlined NASA low-speed GA(W)-1 airfoil and a corrugated dragonfly airfoil at the Reynolds numbers of 68,000 and 55,000. Both 2D and 3D simulations were carried out by solving the unsteady Navier-Stokes equations to predict the behavior of the unsteady flow structures around the airfoils at di...

Compared with straight tunnels, small-radius curved tunnels are more common and have complex influencing factors in urban underground traffic. Therefore, the seismic evaluation of is great significance for safe operation structures. This paper used numerical analysis response surface method to analyze influence buried depth, curve angle radius on a tunnel. For this purpose, seventeen three-dime...

BACKGROUND Anatomic single bundle anterior cruciate ligament (ACL) reconstruction is the current gold standard in ACL reconstructive surgery. However, placement of femoral and tibial tunnels at the anatomic center of the ACL insertion sites can be difficult intraoperatively. We developed a "virtual arthroscopy" program that allows users to identify ACL insertions on preoperative knee magnetic r...

Extensive wind tunnel tests are conducted to evaluate surface pressure distribution of a semi span swept wing. The wing section has a laminar flow airfoil similar to NACA 6-series airfoils. The investigations are conducted at various speeds and angles of attack. Surface pressure distribution over the wing upper surface is measured for both chordwise and spanwise sections. Statistical analyses a...
